TEKTON IMPACT MONITORS

Thank you all for filling me in and the PM's.
TBH, when I am considering a new product, it is precisely the "product bashing" posts that I am most interested in.  Even buying small household items I look for the negative reviews as the most meaningful. The natural human desire to want to "be right" and join a group always skew the positive comments.  I guess that makes me a strange bird to intentionally seek out the bad. 

This morning while Iam listening to my Elac B6 Speakers, while the cd is playing   I heard a familiar scratchy sound on the impact monitors, I raise the the volume and the scratchy sound went away, hours or a day later the voice coil fried.Iam thinking of bringing the amps for a check too.

Are you using a pre amp?
What, or where is the volume controller in your system?
It's kind of unusual that by raising the volume, you reduce a bad noise, that might be an indication of the volume attenuator introducing noise.

Have you checked your volume device, if it's the culprit, you can possibly clean or just outright replace it with something better?

I doubt it’s preamp but I will check, could be tubes on my amps, I can hear the scratch noise on the right side only.
